About half the strength of medium-strength steel coupling nuts, these nuts are for light duty fastening applications.

Made from Grade 5 steel, these inch-sized coupling nuts are suitable for most applications.

Comparable in strength to Grade 9 bolts, these coupling nuts are about 20% stronger than high-strength steel coupling nuts. Available in inch thread sizes.

More corrosion resistant than 18-8 stainless steel coupling nuts, these nuts have excellent resistance to chemicals and salt water.

One-third the weight of steel, aluminum coupling nuts resist corrosion in wet environments.

Stainless steel coupling nuts have excellent corrosion resistance in most environments.

Change thread sizes or types, such as fine to coarse threads, on parts without changing gender.

Connect two differently sized male-threaded parts, such as threaded rods, and tighten with a standard wrench.

Adapt threaded rods from inch to metric. These adapters connect two male-threaded fasteners, so you can change the gender of a mating part or increase or decrease its thread size. The hex-shaped body fits into the head of a standard wrench.

One side inch, one side metric, and a hex in the middle—these handy fasteners connect two female-threaded parts, such as coupling nuts, adapting from inch threads to metric. Tighten with a standard wrench.
